PRESSURE RELIEF VALVE

Product catalog summary
Introduction
This document is the exclusive property of SAPAG VALVES and provides indicative information about their industrial valves.

Performance Specifications
The performance of the valves is dependent on the pressure/temperature ratio, materials, size (DN), and the nature of the fluid. The valves are designed to limit maximum pressure by briefly discharging high flow.

Technical Features
  • Metal-to-metal sealing between nozzle and blanking plate.
  • Quick opening in 1/40th of a second.
  • Adjustable setpoint via a spring acting directly on the blanking plate.
  • Low inertia moving parts.
  • Sealing for upstream pressure below setpoint.
  • No guidance to prevent jamming or parasitic drag.
  • Complete flow discharge with high precision and tightness.
  • Safe actuation.

Conditions of Use
  • Suitable for contaminated, raw, or drinking water.
  • Installed downstream from pumping station pumps or upstream from a shut-off device or overspeed valve.
  • Used in meshed networks with numerous nodes, especially where surges or bursts may occur.

Installation Guidelines
  • Valves should be fitted vertically.
  • Position as close as possible to the component causing pressure surges.
  • Piping connector diameter should be at least equal to the pressure relief valve diameter.

Pressure Relief Valve Specifications
The valve operates effectively between -196°C and 700°C, with a maximum pressure of 100 bar. Specific diameter and pressure ratings are provided for different DN sizes.

Parts List
The document includes a detailed parts list with materials such as S235 JR, galvanized steel, X20Cr13, 17-4 PH, stainless steel, spring steel, and rubber.

Operating Instructions
Instructions for operating the valve 125/32 according to its set pressure are provided, including zones indicating maximum opening and spring wire diameter adjustments.

Conclusion
This document outlines the specifications, technical features, conditions of use, installation guidelines, and operating instructions for SAPAG VALVES' pressure relief valves, ensuring optimal performance and safety.

PRESSURE RELIEF VALVE-1

SAPAG-0036-ENG-2302 The maximum pressures and temperatures depend on the pressure/temperature ratio, materials, size (DN) and nature of the fluid. Performance PRESSURE RELIEF VALVE Limit maximum pressure in a line by discontinuously and briefly discharging high flow. PROTECTING PIPES FROM PRESSURE SURGES Metal-to-metal sealing between nozzle and blanking plate. Quick opening: 1/40th of a second. Adjustable setpoint via spring acting directly on blanking plate. Moving part low inertia. Sealing for upstream pressure below setpoint. No guidance (no jamming or parasitic drag). Tightness and high-precision (honed radius). Safe actuation. Technical features Type of conveyed liquid: • Conditions of use Contaminated, raw or drinking water. In meshed networks with numerous nodes. Generally where surges/bursts may occur. Vertically fitted valve. As close as possible to the component creating pressure surges. Upstream from a shut-off device (valve) or overspeed valve. Downstream from pumping station pumps. Piping connector diameter at least equal to pressure relief valve diameter.
